When replacing your trailer's equalizer and shackle straps it's important to first measure the hole spacing of the current equalizer and shackle straps. The suspension needs to be able to travel back and forth as you go over bumps and when installed correctly will form a "W" (pictured below). Too far inward or outward can bind up your suspension and eventually wear your leaf springs and shackle straps prematurely. Because there's a lot of thought put into this by the manufacturer you'll want to stick with the sizes originally on the trailer.

To measure the equalizer you'll need to measure from center to center of the shackle strap holes (horizontal) and from center to center from the shackle strap hole to the hanger bolt hole (vertical). You'll also want to ensure that you choose the correct capacity for your axle. For example, the Equa-Flex Cushioned Equalizers # LC279687 has a 5-1/2" horizontal measurement, 2-1/2" vertical measurement, and is designed for use on 3K to 6K axles.

To measure for the shackle straps you'll just need to measure from center to center of the holes (pictured below). Since there's no guide for us to look up what was on your trailer I'll need you to measure what the trailer currently has before I can determine the correct replacement parts.
